The worm journal bearing 24, and supporting at its upper 23 on the lower end of vertical shaft 23 revolves end the turn table 25. The vertical shaft 23 is the worm weel 29 and crank 30 to reciprocate '011e journaled at its lower end in the bearing 26 carsleeve 3|, thus in turn reciprocating the pivot 40 ried by the assembling plate 2'I. The said shaftl shaft 32, the connecting rod 34, the feed drive v 23 carries adjacent to the lower end thereof, a shaft 35 and the feed guides 39 and 49. The feed worm, 28, which is meshed with the worm wh-eel guides, in traveling toward the turn-table 25, 2S, to which is aixed the crank 30, which latter impinge with the lugs 62, the end 63' of the actuates a sleeve 3|, freely sliding on the pivot lowermost space-band 64, forcing it under the 45 arm 32. The latter is pivoted at 33 with the feed plate 42, which latter is spring-loaded to connecting rod 34, which is in turn pivoted to press normally downwardly, and place a spacethe feed drive shaft 35 which is secured by means band partly over the table 25. When the guide 36 to the depending arm 3l coupled by threadbars return outwardly of the turn-table the coned means 3B to the feed bars 39 and 49. tact of key 58 with the feed plate 42 pushes said 50 The turn table 25 has an upper surface adapted key forwardly allowing the roller 6| to'rolldownfor polishing.

and the later forward movement of the feed bars and attached plunger will carry the space-band across the revolving polishing surface. It will be understood that the downward pressure of the feed plate on the approximate center of the space band 64 will prevent the latter from being thrown out of the machine until it is gripped by the plunger 54. As one space-band 64 is moved across the turn-table,the lnext in the stack is pushed out in position to be engaged by the plunger, by means of the lugs 62.
